Object Subresources

Amazon S3 defines a set of subresources associated with buckets and objects. Subresources
are
subordinates to objects; that is, subresources do not exist on their own, they are
always
associated with some other entity, such as an object or a bucket.

The following table lists the subresources associated with Amazon S3 objects.

Subresource

Description

acl

Contains a list of grants identifying the grantees and the permissions granted.
When you create an object, the acl identifies the object owner as having
full control over the object. You can retrieve an object ACL or replace it with an
updated list of grants. Any update to an ACL requires you to replace the existing
ACL.
For more information about ACLs, see Managing Access with ACLs.

torrent

Amazon S3 supports the BitTorrent protocol. Amazon S3 uses the torrent
subresource to return the torrent file associated with the specific object. To
retrieve a torrent file, you specify the torrent subresource in your GET
request. Amazon S3 creates a torrent file and returns it. You can only retrieve the
torrent subresource, you cannot create, update, or delete the
torrent subresource. For more information, see Using BitTorrent with Amazon S3.
